SINUMERIK 810D Manual Hardware Configuration (PHC) -- 11.02 Edition
The number of axes on the SINUMERIK 810D can be expanded:
S to five ax es including spindle with CCU2 and CCU1 (< SW 3.1)
S to six axes including spindle with CCU1 (SW 3.1 and higher) and CCU3 (a
closed
-loop control card is required for the 6th axis with CCU1)
There are two ways of doing this:
either an axis expansion plug
-in unit and a SIMODRIVE 611 power
module connected at the axis expansion terminal
or SIMODRIVE 611D closed
-loop control module with SIMODRIVE 611
power module c onnected to the drive bus/device bus
Axis expansion plug--in units are always used when no more than six measu-
ring channels are required for the SINUMERIK 810D. The unit is plugged into a
SIMODRIVE 611 power module. Axis expansion plug
-in units are designed for
1
-axis and 2-axis power modules. The plug--in unit is s upplied complete with
ribbon cables.
If six SINUMERIK 810D measuring channels are not enough, SIMODRIVE 611
closed
-loop control modules must be installed in the SIMODRIVE 611 power
modules to connect further measuring systems (connection via drive bus with
drive bus terminator). When using 611D closed
-loop control modules, it may be
necessary to connect the NCU terminal block to the free drive bus connector on
the 611D closed
-loop control.
See Chapter 5, Axis Expansion
CCU1/2:
1
-axis or 2-axis power modules can be used for axis expansion. 2-axis power
modules can be used for axes and spindles. Power modules must always be
installed on the right of the SINUMERIK 810D.
CCU3:
The new CCU3 can control up to 6 axes “onboard”. A new left expansion plug
-in
unit is available in addition to the existing axis expansion units.
All power sections af the 611D series can be connected for axis expansion as
external power modules.
With SW 3.1 or lower, it is not possible to combine the two types of axis expan-
sion. The number of drives is limited to 5 for CCU1/2.
With SW 6.3 and higher, the limitation for CCU3 is six drives.
Many different drive combinations can be used to implement expansion levels
1--6. If the spindles are to be operated on the internal power module, this must
be connected to the 24A/32A power section (A1).
